Lupinus &#39;LSDRW03-D&#39;

ABSTRACT

A new and distinct  Lupinus  cultivar named ‘LSDRW03-0’ is disclosed, characterized by distinctive bright yellow, fully double, strongly fragrant flowers. Plants uniquely bloom under both short day and long day conditions without vernalization. The new cultivar is a  Lupinus , suitable for ornamental purposes.

Latin name of the genus and species: Lupinus hybrida.

Variety denomination: ‘LSDRW03-0’.

BACKGROUND OF THE INVENTION

new variety, hereinafter referred to as ‘LSDRW03-0’, was discovered as part of a planned breeding program. The intent of the breeding program was to develop Lupine hybrids for commercial ornamental applications.

SUMMARY OF THE INVENTION

The cultivar ‘LSDRW03-0’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘LSDRW03-0’ These characteristics in combination distinguish ‘LSDRW03-0’ as a new and distinct Lupinus cultivar:

-   -   1. Plants uniquely bloom under both short day and long day         conditions without vernalization.     -   2. Pink and white flower coloration.

COMPARISON TO PARENT VARIETY

‘LSDRW03-0’ is similar in most horticultural characteristics to the seed parent variety. Plants of the new cultivar ‘LSDRW03-0’ however, differ in the following characteristics:

-   -   1. The new variety has a different flower color.

‘LSDRW03-0’ is similar in most horticultural characteristics to the pollen parent variety. Plants of the new cultivar ‘LSDRW03-0’ however, differ in the following characteristics:

-   -   1. The new variety has a different flower color.

COMMERCIAL COMPARISON

‘LSDRW03-0’ can be compared to the commercial variety Lupinus ‘West Country Inspiration’. unpatented. Plants of the new cultivar ‘LSDRW03-0’ are similar to plants of ‘West Country Inspiration’ in most horticultural characteristics, however, plants of the new cultivar ‘LSDRW03-0’ differ in the following:

-   -   1. Plants of the new variety produces more inflorescence per         plant, as well as wider inflorescence.     -   2. Plants of the new variety are shorter and sturdier.     -   3. Plants of the new variety will begin flowering without         vernalization, as required by this comparator.

‘LSDRW03-0’ can be compared to the commercial variety Lupinus ‘West Country Blossom’, unpatented. Plants of the new cultivar ‘LSDRW03-0’ are similar to plants of ‘West Country Blossom’ in most horticultural characteristics, however, plants of the new cultivar ‘LSDRW03-0’ differ in the following:

-   -   1. Flower of the new variety medium pink with white, flowers of         this comparator are very light pink with white.     -   2. Plants of the new variety are shorter and sturdier.     -   3. Plants of the new variety will begin flowering without         vernalization, as required by this comparator.
